Nordyne L1RA Air Pressure Switch
The job of the pressure switch is to figure out if the main blower is blowing air. Some pressure switches may have a reset feature that is manual, which forces the system to be reset physically before the entire HVAC system will continue operating again. The air pressure switch is a very critical piece of the collection of safety devices in place to keep you safe from harm.
Signs to Look for when your Pressure Switch is Needing to be Replaced
- Your furnace won't ignite the gas.
- Incorrect electrical voltage running through the pressure switch.
- The desired temperature is almost never fully attained.
